What's really disgusting is the fact that every single person that knew the shooter has said that something "wasn't right" with the guy. Every last one of them knew the guy was weird, and now they're going "huh, didn't see that coming". I've heard different stories that the guy had personality disorders and perhaps autism. Neither have been confirmed yet though.
I blame this tragedy partially on the disregard people hold for the people around them. I'm not really a nosy neighbor or anything, but if this dude were living near me or hanging around my area I'd have kept an eye on him to say the least. Have you guys seen this dudes picture?
Good lord, that is all kinds of creepy. It's like he gazing into my soul with those eyes.
